IMPCO Automotive, a cost effective, designer, manufacturer, calibrator, and installer of innovative bi-fuel and dedicated gaseous fuel systems (CNG/LPG), focused on the North American passenger car, and light- and medium-duty truck alternative fuels markets. IMPCO also obtained certification by the California Air Resources Board (CARB) and Environmental Protective Agency (EPA) for its bi-fuel systems installed in the 2014 Chevrolet Silverado 2500HD and GMC Sierra 2500HD pickup trucks.
As an extension of GM's manufacturing process, IMPCO Automotive installs the single-tank bi-fuel CNG system using GM's OEM processes and standards. The entire gaseous fuel system adheres to GM's strict quality, durability, and safety testing requirements to ensure a superior product. The company’s production facility is in Union City, Ind. Once the fuel system is in place, GM delivers these trucks to a dealer or to an up fitter for customer-ordered modifications.
